Graeme, I am not familiar with device driver for embedded Linux, but I think the Linux device driver for Atom currently still use the BIOS alike support at least in the booting phase.
I think there may be a challenge to port the device driver (video, SATA, ethernet, etc.) to use in uboot from one Atom to another different Atom, unless uboot can reuse directly the device option rom that provides the int services and the device driver that uses the int services in the booting phase. I assume coreboot will be able to have such reuse. However I still see a value to uboot (without PC support) for deeply embedded application using certain Atom.
